Summary
This study compared daylighting performance between clerestory and standard view windows in an affordable housing bedroom, measuring shade configurations and daylight factors over a three-day period. Findings can inform window design choices in residential settings where adequate and controllable daylight exposure supports occupant circadian health and wellbeing.
Key Findings
- Data collected over a three-day period using photometric sensors in a physical model to assess daylight factor under different shade configurations
- Study was largely qualitative due to resident non-participation; quantitative results focused on shade use patterns and daylight factor comparisons between clerestory and standard glazing units
- Resident shade use behavior was observed to determine real-world daylighting conditions versus theoretical window performance
Categories
Sleep & Circadian Health: Daylighting levels in residential bedrooms directly affect light exposure patterns relevant to circadian entrainment and sleep quality.
The Science of Light: Study measures daylight factor using photometric sensors across different window/shade configurations, providing empirical lighting performance data.
